I doubt that it's Pitch Pine. A lot of old, well-coloured pine is referred to as Pitch Pine when it's actually just old Scots Pine or (sometimes) Douglas Fir. PP tends to warp easily, due to its uneven growth, so it's probably not very suitable for doors. And it's certainly not Parana Pine - the grain's too wild and knotty.
The "red powdery stuff" in the knots might be patent knotting or just resin.
I can understand your desire not to paint it, Rob, and that being the case I - like worms - would linseed oil it. But if that's what you're going to do, I fear you've still got a lot of preparatory work on your hands to get rid of the paint residues. And if you want to conserve the graffiti you'll have to avoid sanding it.
I reckon boiled linseed will be better, as it dries more quickly. Raw can stay sticky for a long time and dust sticks to it.
By the way, you do know about the dangers of linseed-oily rags, don't you? If you leave them screwed up, they can spontaneously ignite. So it's always safer to wash them out and leave them spread flat to dry.
